avast 2014.9.0.2011 is mature.
You just must not update but perform a clean install.
- Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition
Note : You need to be ONLINE during the install (sometimes online installer works whereas offline doesn’t)

Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/
- Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
- Uninstall in safe mode using Avastclear.
- Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
- Install the version you downloaded.
- Reboot.
As far for the shutdown, have you checked the power saving settings on the systems?
Both in windows as well as in the bios?
